Amsler Announces Availability of Servo Stretch Rods for Complete Line of Stretch-Blow Machinery

Key Benefits Include Precision Control, Energy Savings, and Greater Output

ORLANDO, Fla., April 1, 2012 – Amsler Equipment Inc., a leading manufacturer of all-electric, reheat stretch blow molding machines based in Richmond Hill, Ont., Canada, has announced the availability of highly-efficient servo stretch rods for its complete line of all-electric reheat stretch-blow machinery. The company has already sold several convertible L32 three-cavity reheat stretch-blow molding machines with servo stretch rods in North America. Amsler made the announcement at NPE 2012: The International Plastics Showcase, April 1-5, 2012 at the Orange County Convention Center in Orlando, Fla. (Booth #583).

For custom blow molders, the servo-driven electric stretch rods deliver major productivity advantages over pneumatic stretch rods, according to President Werner Amsler. “We’ve taken an already highly efficient machine and made it even more energy efficient,” said Amsler. “Our machines are now able to offer a new level of cost savings and at the same time increased output.”

Compared to pneumatic versions, servo stretch rods provide the user with more precise control over the stretching process and reduced cycle time, said Amsler. Servo stretch rods also provide lower power consumption, saving 5 kW/h of energy. They also offer more precise and better speed control and ramp-up for better productivity and consistency, thus reducing scrap.

A 4% cycle time reduction results in improved productivity which means more bottles per hour. Operator setup of servo stretch rods is easier compared to pneumatics because no tools are required and they are automatically set up

through the existing operator interface. Unlike pneumatic cylinders which eventually require rebuilding, servo stretch rods require no maintenance.

Servo stretch rods are offered as an option on all of Amsler’s all-electric reheat stretch-blow molding machines.
